How to write a recursive function.

It can be assumed that the delta t, delta theta is equal to the 20th
The next step is to check the condition (ca) and then calculate the delta theta.
And so to the end of the range t
Can somehow save the studio smath

laikluk,

As you can see you can write recursive functions in SMath. You have to include a test for a terminating value otherwise it will continue to call itself.

I've provide an example of the greatest common denominator and tested against some values from the internet. Good luck with your function.
